Abstract

A form fit liner for a container has a bottom wall and at least one sidewall formed of at least one layer of a flexible material, at least one heat seal joining two adjacent portions of material of the sidewall and extending from the bottom wall towards the upper edge of the liner to define a reduced cross-sectional area lower portion of the liner constructed to be received within the container and an upper liner portion having a greater cross-sectional area than the lower portion constructed to extend out of the container to isolate the container from its contents as the liner is filled and emptied. The upper portion of the liner which extends above the container can surround a fill tube used to dispense a liquid product into the liner of the container to shield the container from the splashing or sloshing of the liquid product as the container is being filled. If desired, the upper portion may be folded down over a portion of the outside of the container to similarly isolate the container from the contents thereof as the container is filled or emptied. The increased cross-sectional area of the upper portion facilitates folding the upper portion over the container, and especially over insulated containers, such as those used for ice cream, which have a significant wall thickness.
